OK, makes sense. But it should already work this way: we now have in libsdp.conf match_both listen *:12865 # match listen *:21 match_both listen *:22 match program * And match program * should cause everything to go over SDP by default. So you either have a modified libsdp.conf (could you post it please?) or there's a bug in libsdp. -- Michael S.
